I'm quite sceptical about pipelining.
I disagree. Even without reading the post you mention, we already
noticed that since this version everything is working much faster than
with prior versions. We have a lot of stuff implemented with Python-SDK
but on one of them the effect is quite notorious: A script checks VMs'
permissions and takes decisions based on them. Without pipelining this
script took about 5 minutes to execute, with pipelining it doesn't take
more than 15 seconds on a ~1000VMs infrastructure.

It also talks about multiple connection, but don't use
pycurl.CurlShare(). I thing this might be very helpfull, as it allows
to share cookies, see
https://curl.haxx.se/libcurl/c/CURLOPT_SHARE.html.
